Host Cell Protein Testing Explained

Host Cell Proteins (HCPs) are process-related impurities that originate from the cells used to manufacture biologic products. Monitoring HCP levels is an important part of biologics quality assessment. Why HCP...

Residual DNA Testing in Biologics Development

In biologics and advanced therapy workflows, monitoring residual DNA is an important part of impurity assessment. Residual host cell DNA may remain after purification and must be carefully evaluated. Why It...

Mycoplasma Contamination: Causes and Prevention

Mycoplasma contamination is one of the most common problems in cell culture research. It can affect cell growth, metabolism, and gene expression, leading to unreliable data. Common Causes Introduction of...

ELISA vs Western Blot for Protein Detection

Two of the most commonly used protein analysis methods are ELISA and Western Blot. Both techniques are valuable, but they answer different experimental questions. Advantages of ELISA Well suited for quantitative...

How to Optimize Transduction Efficiency

Achieving high transduction efficiency is critical in many gene delivery experiments. For AAV and lentiviral workflows, optimization often requires multiple parameters to be adjusted together. Key Factors to Optimize Accurate viral...
